### RTPEngine + RTIMER + SEGFAULT + unable to ping When unable to ping RTPEngine instances kamailio crashes. ### Troubleshooting Determined issue was related to the ping failures, resolved AWS SG issue, allowing successful pings. Issue subsequently went away. #### Reproduction Use rtpengine with RDS backend Load rtpengine with ~ 20 destinations you do not expect a response from on Use rtimer to call rtpengine.reload via jsonrpcs: ``` modparam("rtimer", "timer", "name=rtpengine;interval=60;mode=0;") modparam("rtimer", "exec", "timer=rtpengine;route=RELOAD_RTPENGINE") route[RELOAD_RTPENGINE] { xinfo("RTPEngine database reloading"); jsonrpc_exec('{"jsonrpc": "2.0", "method": "rtpengine.reload", "id": 1}'); } ``` #### Debugging Data Got a core dump -- although I deleted quickly (not thinking) as they were running instances out of disk quickly. bt full did not show much to step through all though clearly pointed to rtpengine. #### Log Messages ``` send_rtpp_command(): timeout waiting reply for command "ping" from RTPEngine <udp:10.0.X.X> ``` ### Possible Solutions TBD / do not have ping failures under heavy load. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.8.2 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_SEND_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 10.2.1 ``` * **Operating System**: ``` uname -a Linux 5.10.0-27-cloud-amd64 #1 SMP Debian 5.10.205-2 (2023-12-31) x86_64 GNU/Linux cat /proc/version Linux version 5.10.0-27-cloud-amd64 (debian-kernel(a)lists.debian.org) (gcc-10 (Debian 10.2.1-6) 10.2.1 20210110, GNU ld (GNU Binutils for Debian) 2.35.2) #1 SMP Debian 5.10.205-2 (2023-12-31) lsb_release -a No LSB modules are available.
